2. Clean the primary element using low air
pressure (30 PSI or less). Blow dust from the
inside to the outside of the element (opposite
to normal air flow through element).
IMPORTANT: Be careful not to rupture the
filter element. Maintain a safe distance
between the air nozzle and the filter element
when directing air up and down the clean air
side of the element pleats.
3. After cleaning the element, check the inner
diameter seals for damage. If damage is
present, replace the primary element.
Change the element after six cleanings or
once a year.
4. Reinstall the primary element by inserting it
into the canister and pushing on the end of
the element until it is seated against the
canister.
NOTE: Place a light inside the element to
check for paper leaks or for bonding of
the paper to the end plate. If any leaks are
found, replace the element.
NOTE: If element is not inserted far
enough into canister, the end cap cannot
be installed.
5. Place the end cap onto the canister body
and attach spring clamps. Make sure the end
cap is locked in place and not loose.
IMPORTANT: Never tap the element with
hard objects or against a hard surface. This
may dent or break the element end cap
seals.
ATTENTION: Failure to obtain a good seal
between elements and the canister may
cause major engine damage.
Air Cleaner Inner Safety Element
NOTE: For maximum engine protection and
air cleaner service life, install a new inner
safety element every third primary element
change or after every 1000 hours of
operation, whichever comes first.
The air cleaner inner safety element
A
cannot
be cleaned. It must be replaced once it
becomes partially clogged. A clogged element
will cause an air restriction resulting in a loss of
engine power or excessive black exhaust
smoke.
NOTE: Conduct a visual inspection of the
inner safety element by placing a light inside
the element. Little or no light will shine
through the element if it is partially clogged.
To remove the inner safety element, pull it out of
the canister body.
To install the new element, push it into the
canister until seated.
IMPORTANT: Clean any dirt from the canister
before installing the inner safety element. Check
element inner diameter seals for damage and
replace the safety element if seal damage is
present.
ATTENTION: Failure to obtain a good seal
between the filter and canister may cause major
engine damage.
